Chemists create 'Superbowl' molecule; May lead to better health

...e difficult for things to pass in and out. This is ideal if you're trying to capture certain molecules and hold them until they're ready for release, the researcher says. Superbowl molecules are similar in function to buckyballs, the experimental soccer-ball shaped molecules also known as fullerenes (C60)...

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

...ze the details. "We see the SPIM technology as an ideal approach for satisfying the growing demand in highly resolved image information from living organisms. The products based on this technology will form a perfect match with our lines of confocal and multiphoton 3D-imaging systems," says Dr. Simon. Th...

Live Recombinant Adenovirus Vaccine Technique Explored

...V vaccines currently in clinical trials may not be ideal in poorer countries because they are expensive and require multiple immunizations. The Hopkins researchers developed their vaccine prototype using canine oral papillomavirus (COPV), which behaves similarly to HPV. Research by other scientists showed...

Researchers reveal the infectious impact of salmon farms on wild salmon

... packed salmon, are aquatic feedlots providing the ideal conditions for the breeding and spread of sea lice amongst the adult fish. For the migrating wild salmon, the farm is a concentrated point source of infectious lice larvae. "We found lice levels exceeded what we would find normally, extending for 30...

Spider Venom Could Yield Eco-Friendly Insecticides

...bite that is deadly to humans and insects -- is an ideal source of venom for King's research. The spider "cooperates" by rearing up in a fighting stance when provoked, making it relatively easy for researchers to aspirate venom directly from its fangs. Since Australian funnel-web spiders can live for more ...

Scientists develop new color-coded test for protein folding

... on the acidity of the solution, thus making it an ideal tool for detecting conformational changes in proteins. "While we're not ready to mass-produce this technology, we believe it will eventually be useful for testing other, more complicated proteins," Zare said, noting that a gold nanoparticle sensor c...

Same mutation aided evolution in many fish species, Stanford study finds

...ized new freshwater lakes and streams, they are an ideal model for understanding how animals adapt to their unique environments. The recent work carries a few surprises. Kingsley said that the gene in question, called Eda, is an old friend to laboratory researchers who have found that mutations in the sam...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

...e the zebrafish, because its transparent embryo is ideal for observing developmental events. They injected individual CNEs into embryos, along with a green fluorescent protein (GFP) reporter. By day two of development, 23 out of 25 CNEs injected had upregulated GFP expression, indicating interaction of the...

Love at first smell

...ent MHC molecules would provide offspring with the ideal number of MHC types. However, when the perfume was added to males that already had the ideal range of MHC molecules, females could also be fooled into believing that these males smelled repulsi...

WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

...selves, but once diluted by rains, they can become ideal breeding places for the malaria vector. Drinking water storage around temporary dwellings can also become a breeding place for vectors. Exposure is further increased if displaced populations live in temporary conditions without proper shelter. Diffe...

Gene therapy promising for growing tooth-supporting bone

...eins peaked after a week. Giannobile said that was ideal because the team did not want to make any permanent genetic changes. The gene acted quickly to get bone growth started, then disappeared within about 28 days. Giannobile said a next step in this process could include looking for non-viral approaches...

Birds brains reveal source of songs

...tive, trial-and-error type of learning provides an ideal model for studying similar processes in humans, such as how a baby's babble takes on the conversational cadences and recognizable syllables of mama and papa. Likewise, the brain pathways involved in birdsong have a human counterpart, the poorly under...

NASA study finds snow melt causes large ocean plant blooms

... upwelling of cooler nutrient-rich water, creating ideal conditions for phytoplankton to bloom every year during summer. Since 1997, a reduction in snow has led to wider temperature differences between the land and ocean during summer. As a consequence, sea surface winds over the Arabian Sea have strength...

UNC launches study of liver injury caused by drugs

...drugs, he added. "Drug-induced liver injury is an ideal model to study how genes and environment interact to produce disease in some but not all people. We hope the factors identified by DILIN research will provide clues to susceptibility to the many diseases that represent an interaction with the environ...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...avid Larom and his co-workers proposed that, under ideal atmospheric conditions, low-frequency calls could travel 6 miles or more through the air. Now in private industry, Larom has long been intrigued by O'Connell-Rodwell's work. "This is important basic research," he says. "Like all creatures, humans pe...

Turning viruses into allies against cancer

...ion of this receptor thus makes liver cancer cells ideal targets for the measles virus. The results confirmed widespread infectivity, toxicity and destruction among these cells, probably through apoptosis or programmed cell death. When the modified virus was injected directly into human liver cancer cells...

New project aims to make large-scale lobster farms feasible

...pecies a reality, " she said. Spiny lobster is an ideal target for commercial culture due to its high value and limited availability from wild capture, mostly using traps. Each year, 3 to 4 million pounds of Florida spiny lobsters valued at about $17 million are harvested and account for 11% of the spiny ...

Finding hidden invaders in a Hawaiian rain forest

...ote sensing program has focused on the area as the ideal outdoor research laboratory for devising the next generation of aircraft and spacecraft observations. Now we've added a major focus on the application of our techniques to invasive species problems in the Hawaiian Islands. It is a win-win combination...

Researchers pioneer new gene therapy technique using natural repair process

...disease, they are not always successful. "SCID is ideal for this sort of therapy because you only need to correct the defect in a small number of immune cells to fix the problem," said Dr. Porteus, assistant professor of pediatrics and biochemistry at UT Southwestern. "This is called selective advantage; ...

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

...uch as mice. The mouse has long been considered an ideal laboratory model for studying human development and disease, primarily because mouse DNA and human DNA are remarkably alike. The MADM technique, which Luo and his colleagues developed for mice, works on the same principal as the method currently use...
